The Short Answer
A full bathroom remodel requires a permit in Homer Glen if you relocate any plumbing fixtures, add new electrical circuits, install a new exhaust fan, change a tub-to-shower configuration, or move walls. Surface-only work (tile, vanity, faucet swap in place) is exempt.
Homer Glen Building Department requires permits for bathroom remodels that involve fixture relocation, electrical upgrades, or plumbing system changes — which describes most 'full' remodels. What's unique to Homer Glen specifically: the city adopts the current Illinois Building Code (IBC), which tracks the 2021 IRC, and enforces those standards through plan review with no separate 'expedited' track for small bathrooms like some suburbs offer. Homer Glen's permit portal accepts applications online, but the department still requires full paper or PDF submittals for plan review — not all Will County communities do both. The city sits on glacial till and clay-bearing soil with a 42-inch frost depth (tied to Chicago standards), which affects any plumbing work below grade. Permits cost $300–$800 depending on job valuation, and plan review typically runs 2-3 weeks. Owner-occupied bathrooms can be permitted by the homeowner; contractor-pulled permits require the contractor to be licensed in Illinois.

What happens if you skip the permit (and you needed one)

Homer Glen full bathroom remodels — the key details

The Illinois Building Code (adopted by Homer Glen) requires a permit for any bathroom remodel that involves plumbing fixture relocation, new electrical circuits, a new exhaust fan, tub-to-shower conversion, or structural changes. IRC P2706 governs drainage-fitting installation; if you're moving a toilet, lavatory, or shower drain more than a few feet, the new drain arm cannot exceed a slope of 1/4 inch per foot horizontal run, and the trap must be within 30 inches of the fixture drain outlet (measured along the pipe). Most relocations bump against these limits and require engineered review. Similarly, IRC M1505 requires exhaust fans to duct directly outdoors (not into the attic or soffit) with a damper; Homer Glen inspectors specifically check for ductwork termination and damper operation during rough inspection. If you're converting a tub to a shower or vice versa, IRC R702.4.2 demands a complete waterproofing assembly (cement board or equivalent + waterproof membrane) behind the tile. Many contractors cut corners here by just tiling over drywall; the city's plan review will catch it, and the inspector will reject rough-in.

Homer Glen enforces IRC E3902 for GFCI protection: all receptacles within 6 feet of a sink, in a tub/shower enclosure, or near standing water must be GFCI-protected (either the outlet itself or the circuit breaker). Bathroom lighting and exhaust fans can be on a standard 15 or 20 amp circuit, but if you're adding a heated floor or towel warmer, that's often a dedicated 20 amp circuit with its own breaker and GFCI protection. The city's electrical inspectors are thorough; your submittal must show GFCI location, circuit amperage, and wire gauge. Many homeowners forget to note that a bathroom circuit serving a Jacuzzi tub or sauna requires 240V and its own dedicated breaker — this triggers a larger permit and higher fees if you didn't budget for it. Pre-1978 homes (common in Homer Glen's older neighborhoods near Wolf Road) fall under the Illinois Lead Rule: any work that disturbs lead paint requires a licensed lead-abatement contractor or certified renovator. You don't need a separate lead permit, but you must notate it on your bathroom remodel application.

Exemptions: In Homer Glen, you do NOT need a permit for replacing a faucet, toilet, towel bar, or vanity in the same location, or for retiling walls/floors over existing surfaces (provided you don't relocate any drain). Similarly, replacing an existing exhaust fan with the same model (same duct and termination) is exempt; if you're moving the fan to a new wall or changing duct routing, a permit is required. Vanity swap (cabinet only, same plumbing connection) is exempt. However, many homeowners discover mid-project that they need to reroute a drain or add a new electrical outlet to the vanity light, which then triggers a full permit. Homer Glen Building Department recommends pulling a permit upfront if there's any doubt — the $300–$400 fee is cheaper than a stop-work order mid-demo.

The glacial till and clay soils around Homer Glen (especially in the areas south of US Route 6) mean plumbing work below the frost line (42 inches) must account for seasonal groundwater and clay expansion. If your bathroom sits over a crawlspace or has a below-grade drain line, the inspector will verify that the line is properly sloped, vented, and protected from frost heave. Newer homes in Homer Glen's subdivisions (post-1980s) rarely have below-grade bathroom drains, but older homes near the Hickory Creek corridor sometimes do. Any sub-frost plumbing requires special inspection during rough-in. The city's permit office is responsive to phone and email questions; call ahead to clarify whether your specific fixture relocation or electrical upgrade triggers plan review or can be flagged as 'standard' (faster approval).

Timeline and fees: Permit application costs $300–$800, typically 1.5-2% of the total project valuation (so a $15,000 bathroom remodel draws a $300–$400 permit). Homer Glen's plan review runs 2-3 weeks for standard bathrooms; complex relocations with new electrical and HVAC ductwork can stretch to 4 weeks. Once approved, you'll schedule rough plumbing and rough electrical inspections (same day possible), then framing (if walls are moved), drywall, final plumbing, final electrical, and final building inspection. Most full remodels pass final on the first or second try if the rough inspections are clean. The city does not require a separate UCC (Uniform Construction Code) sign-off for bathrooms, but your contractor may pull separate electrical and plumbing licenses depending on scope — that's on the contractor, not you. Keep your permit card and inspection sign-offs; you'll need them for closing if you refinance, and the title company will ask for proof of permitted work.

Three Homer Glen bathroom remodel (full) scenarios

Scenario A
Bathroom vanity and faucet replacement, same location (no plumbing relocation) — split-level home near Wolf Road, Homer Glen
You're replacing the old ceramic pedestal sink with a modern wall-hung vanity, same wall location, same supply and drain lines. No new electrical circuits, no exhaust fan change, no walls moved. This is a pure fixture-swap, which is exempt under Illinois Building Code and Homer Glen's local amendments. No permit required, no inspection needed. You do not need to notify the building department. However, if the existing supply lines are corroded copper and you're installing new PEX or PVC lines even to the same connection points, that's still considered in-place replacement and remains exempt. The only caveat: if your home was built before 1978 and the vanity cabinet removal disturbs paint (very common on older pedestal sinks with paint-sealed trim), you must follow lead-safe work practices — containment, HEPA vacuuming, clearance test. Lead abatement itself doesn't require a permit, but documentation is wise for resale disclosure. Total cost: vanity $400–$1,200, plumber labor $300–$600, no permit fees.
No permit required | In-place fixture swap exempt | Lead-safe practices if pre-1978 | Total cost $700–$1,800 | No inspections
Scenario B
Full master bath gut-remodel with toilet/shower relocation and new exhaust duct — ranch in Pinewood subdivision, Homer Glen
You're moving the toilet from the south wall to the north wall (8 feet), relocating the shower pan 4 feet east, and adding a new exhaust fan ducted through the exterior wall (current home has no bathroom ventilation — common in 1970s-80s Homer Glen ranches). This requires a full permit and plan review. The toilet relocation triggers IRC P2706 inspection: the city inspector will verify that the new drain arm has proper slope (1/4 inch per foot), that the trap is within 30 inches of the fixture outlet, and that the new vent line is properly sized and routed. You'll need a rough plumbing inspection before you close up walls. The shower relocation means a new shower pan, supply lines, and drain; if you're converting a tub to a shower (different fixture type), IRC R702.4.2 requires a waterproofing assembly — cement board and membrane, or a pre-fabricated waterproof pan. Homer Glen inspectors specifically flag showers tiled directly over drywall and will reject rough-in. The exhaust fan must be ducted to the exterior (IRC M1505), not to the attic or soffit — the city's plan review will require submittal showing the duct route and exterior termination point, including damper. You'll need a new 20-amp circuit for the exhaust fan (and likely for a heated floor if you're adding one). Permit cost $500–$700. Plan review 2-3 weeks. Inspections: rough plumbing, rough electrical (if circuits added), drywall (if new walls), final plumbing, final electrical, final building. Total project cost $12,000–$20,000 depending on finishes and whether you're also moving the vanity. Estimated timeline: 8-12 weeks from permit to final inspection.
Permit required | Full plan review 2-3 weeks | Rough plumbing + electrical inspections | IRC P2706 drain slope verification | IRC R702.4.2 shower waterproofing required | Exhaust duct termination exterior-mandated | Permit cost $500–$700 | Total project $12,000–$20,000
Scenario C
Bathroom addition: new half-bath in former closet with new plumbing rough-in — 1950s cape-cod in south Homer Glen (clay-soil area)
You're carving out a small half-bath from an existing closet: new toilet and wall-hung sink, no existing plumbing in that area, so you're running new supply and drain lines from a remote location. This is technically not a 'remodel of existing bathroom' but rather a 'new fixture installation,' which requires a full permit and plan review. Homer Glen treats this as a new plumbing system addition, not a bathroom remodel, so the code path is stricter. You'll need to show on your submittal: new vent line routing, drain slope compliance, trap distance (IRC P2706), GFCI protection (IRC E3902 — at least one outlet in the half-bath must be GFCI), and exhaust fan (IRC M1505 — even a half-bath needs ventilation, though a smaller fan may suffice). The soil in south Homer Glen is clay-bearing with seasonal groundwater; if your new drain line goes below the frost line (42 inches), you must specify that the line is properly vented and sloped, and the inspector will want to verify during rough inspection. Plan review will be thorough because the inspector cannot assume existing conditions; you're essentially describing a new plumbing island. Permit cost $400–$600. Plan review 3-4 weeks (longer than a typical remodel because there's no existing system to tie into). Rough plumbing and rough electrical inspections required. Drywall inspection if new walls. Final inspections. Total project $4,000–$7,000. Timeline 10-14 weeks.
Permit required (new fixture installation, not remodel) | Full plan review 3-4 weeks | Requires vent and drain design | Frost-line soil consideration (42 inches) | GFCI and exhaust fan mandated | Permit cost $400–$600 | Total project $4,000–$7,000

Waterproofing assemblies for tub-to-shower conversions in Homer Glen bathrooms

When you convert a bathtub to a shower or install a new shower in a bathroom remodel, Homer Glen Building Department enforces IRC R702.4.2, which mandates a complete waterproofing assembly behind all wall tile and under the shower pan. This is one of the most commonly rejected items in plan review and rough inspection. The code requires either a cement board (minimum 1/2 inch) bonded to studs with waterproof adhesive, plus a liquid or sheet membrane applied over the cement board, or a pre-manufactured waterproof panel system. Many DIY and budget contractors try to tile directly over drywall or use caulk as a waterproofing layer — Homer Glen inspectors will reject this and require removal and reinstallation. Cement board + membrane is the most common and cost-effective solution: expect $300–$600 in materials plus $400–$800 in labor for a typical master shower. Schluter or comparable waterproof corner and trim systems are required to prevent water intrusion at edges and transitions.

The city's inspectors pay particular attention to the shower pan itself. If you're using a pre-formed acrylic or fiberglass pan, you're mostly safe — the manufacturer's installation specs suffice. If you're building a custom tile-on-mortar pan (traditional method), the code requires a waterproof membrane (CPE liner or equivalent) below the mortar bed, proper slope toward the drain (1/4 inch per foot), and a mortar bed depth of 1 1/2 to 2 inches. Pre-slope (a slight slope cast into the concrete floor before the membrane) is optional but strongly recommended in Homer Glen's older homes, where subfloor settling sometimes creates low spots. Water pooling under a shower is the #1 cause of wood-rot callbacks. The rough inspection occurs before you tile, so inspectors will verify membrane sealing at all corners, penetrations, and edges — caulk alone is not acceptable.

For budget-conscious remodels, pre-manufactured waterproof shower surrounds (three-piece or larger fiberglass units) avoid the membrane-and-tile assembly entirely and pass inspection easily. They cost $800–$2,000 installed and eliminate waterproofing risk. However, they're visually less flexible and may not fit custom shower sizes. If your project is a full master-bath remodel with a large custom shower, plan for a 7-10 day delay while the waterproofing membrane cures before you tile — this is not always budgeted into tight timelines.

Electrical and GFCI requirements for Homer Glen bathroom remodels

Homer Glen enforces IRC E3902, which mandates GFCI (ground-fault circuit interrupter) protection for all bathroom receptacles within 6 feet of a sink, and for any outlet inside a tub or shower enclosure. This applies to vanity lights (if they have a receptacle), heated towel racks, ventilation fans with receptacles, and any other outlet in the bathroom. You have two options: install individual GFCI outlets at each location (more expensive upfront, but easier to reset if tripped), or install a GFCI circuit breaker at the panel and run standard outlets downstream (one breaker protects the whole bathroom circuit). Most remodels use a dedicated 20-amp GFCI breaker feeding the vanity and other outlets; this requires the circuit to be run during rough electrical inspection. If you're adding a heated floor mat or towel warmer (common in high-end remodels), that often requires its own dedicated 20-amp circuit because those loads can exceed the bathroom circuit capacity.

One frequently missed requirement: if your bathroom remodel involves moving any walls or adding new outlets within 6 feet of a sink, you must also check for AFCI (arc-fault circuit interrupter) compliance. Bedrooms and living spaces require AFCI protection, and bathrooms sometimes do depending on the specific circuit routing. Homer Glen's electrical inspectors will flag this during plan review if your submittal doesn't address it. A typical mistake is running a bedroom or closet circuit into the bathroom without AFCI; the revised circuit must be protected. This often requires a new breaker at the panel and can delay final electrical inspection by a week if caught late.

If you're upgrading to a heated floor or a luxury fixture (Jacuzzi, steam shower), those often require 240V and dedicated circuits — a 50-amp service upgrade may be needed if your home's panel is near capacity. Homer Glen has many 1970s-80s homes with 100-amp service, which can be marginal if you're adding multiple new circuits. The city's electrical inspector will flag this at rough inspection and may require a service upgrade before final approval. Plan for this possibility and budget $1,500–$3,000 if you think you'll need it — it's easier to upgrade during a bathroom remodel than later. Your contractor should verify panel capacity early in the design phase.

Common questions

Do I need a permit if I'm just replacing my bathroom vanity and faucet with new ones in the same location?

No permit needed for in-place fixture replacement. Swapping a vanity or faucet at the existing connection points is exempt in Homer Glen. However, if your home was built before 1978, the removal may disturb lead paint — you must follow lead-safe work practices (containment, HEPA vacuuming). If you're upgrading the supply lines even to the same location (e.g., old copper to new PEX), that's still considered in-place and exempt.

What's the cost and timeline for a full bathroom permit in Homer Glen?

Permit cost ranges from $300–$800 depending on project valuation (typically 1.5–2% of total bathroom cost). Plan review takes 2–3 weeks for standard remodels; complex relocations may stretch to 4 weeks. Once approved, inspections (rough plumbing, rough electrical, final) typically occur over 4–8 weeks depending on contractor scheduling. A full bathroom remodel from permit approval to final inspection usually takes 8–12 weeks total.

If I move a toilet or shower drain, what does Homer Glen require on the permit application?

Your application must show the new drain location, slope (IRC P2706 requires 1/4 inch per foot, maximum), trap distance from the fixture (maximum 30 inches along the pipe), and vent line routing. Homer Glen's plan review will verify that the new drain arm doesn't exceed the maximum slope and that the trap is properly sized. If you're unsure of these measurements, a licensed plumber or draftsperson can prepare a simple sketch — it doesn't need to be professionally engineered unless the run is very complex.

Is a new exhaust fan always required for a bathroom remodel in Homer Glen?

If your bathroom currently has no exhaust fan, adding one is not required by code for a cosmetic remodel, but it is recommended for moisture control and is required if you're doing a gut remodel or converting a tub to a shower. If you're adding a fan, it must duct directly to the exterior (not attic or soffit), include a damper, and be properly sized per IRC M1505. Adding a new fan triggers a permit and rough electrical inspection.

What's the difference between a bathroom remodel permit and a bathroom addition permit in Homer Glen?

A remodel of an existing bathroom requires a permit if you're relocating fixtures or changing systems. A new bathroom addition (adding a bathroom where one didn't exist) follows a stricter code path because there's no existing system to tie into — plan review is typically longer (3–4 weeks) and fees may be higher ($400–$600+). If you're adding a half-bath in a former closet, Homer Glen treats it as a new fixture installation, not a remodel.

Can I pull my own bathroom permit in Homer Glen, or does my contractor have to do it?

Homer Glen allows owner-occupied homeowners to pull permits for their own homes. You do not need a contractor's license to apply. However, if a contractor performs the work, they must be licensed in Illinois (Plumbing, Electrical, or HVAC as applicable). Many contractors prefer to pull the permit themselves to maintain control of the schedule. Confirm with Homer Glen Building Department whether you can file online or must submit paper applications in person.

If my home was built before 1978, what do I need to know about a bathroom remodel?

Pre-1978 homes in Homer Glen are subject to the Illinois Lead Rule. Any work that disturbs lead paint (common in older vanities, trim, and fixtures) requires lead-safe work practices: containment, HEPA vacuuming, and clearance testing. You do not need a separate lead permit, but you must disclose the use of lead-safe practices on your bathroom remodel application. Hiring a certified lead-abatement contractor or renovator adds $500–$1,500 to the project but is required if you disturb paint.

What happens during a rough plumbing inspection in Homer Glen?

The inspector verifies that all new drain lines have proper slope, that traps are correctly sized and positioned, that vent lines are routed correctly, and that new supply lines are properly supported and protected. The inspector will also check that drains are not blocked and that the system is ready for pressure testing (if required). Rough inspection occurs before drywall is closed up. Most inspections pass on the first visit if the work follows code; if there's a violation (e.g., a drain slope that's too steep), the plumber must correct it and you'll reschedule inspection.

Do I need a waterproofing plan or specification for my shower tub conversion?

Yes. Your permit application should note the waterproofing method: 'Cement board + liquid membrane,' 'Schluter waterproofing system,' 'Pre-formed fiberglass pan,' or similar. Homer Glen's plan review will flag any missing waterproofing specification and require you to clarify before approval. The rough inspection occurs before tiling, so the inspector will verify that the membrane or pan is properly installed. This is one of the most frequently caught defects in bathroom remodels.

Can I do a partial bathroom remodel without a permit (e.g., just tile and vanity)?

Yes, if you're only replacing tile, vanity, faucet, or toilet in place (no relocations, no new electrical, no new ductwork), no permit is required. However, if any part of your project involves moving a fixture, adding a circuit, or changing plumbing or HVAC routing, you must pull a full permit. Homer Glen Building Department recommends calling ahead if you're unsure whether your scope triggers a permit — the phone consultation is free and clarifies upfront.
